First, you cut out a small piece of tissue from an animal. You then place the tissue in a cultivator that mimics the inside of a living organism. You provide the cells with warmth, oxygen, sugars, salts, and proteins, and cultured meat eventually grows big enough eating. Supporters are willing to point out the benefits of cultured meat. It does not involve killing animals. environmentally-friendly. According to scientists, cultured meat would require about 40 % less energy to produce than the same volume of pork or beef. Cultured meat is also

Luckily, the amount of shale gas and oil buried in the US is large enough to last 100 years. ( ) Up to now, the US has been importing about half its energy demand. ( ) Thanks to the discovery of shale energy, the United States is going to become an energy-exporting country. ( ) The problem lies in the extraction process of shale gas. ( ) To extract the gas and oil, people use a

( ) Then they put pressure on the rock using a large amount of water in order to break it and (C) release / releasing causes water shortage and can even cause earthquakes near the shale energy mines. Nevertheless, people remain very interested in shale energy. This is because the world is running out of other energy sources. the gas and oil. This * fracking ( ) However, as everything has its pros and cons, so does shale gas.
